SPEOIFIGATIbN forming part of Letters Patent No. 780,463, dated January 17, 1905. Application filed March 23, 1904. Serial No. 199,569.

To all whom it may concern.-

Be it known that I, NEWTON L. WARREN, a citizen of the United'States, and a resident of Macon, in the county of Bibb and State of Georgia, have invented a new and Improved Locomotive-Boiler, of which the followingis a full, clear, and exactdescription.

The object of the invention is to provide a new and improved locomotive-boiler which is simple and durable in construction and arranged to provide a clear space between the fire-box and the wagon-top unobstructed by stays or the like. i

a The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.- Apractical embodiment of the invention is represented in the accompanying drawings,-

forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal central section of the improvement. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1. Fig. 3 is an enlarged cross-section of the improvement on the line 3 3 of Fig. 1. Fig. 4 is a longitudinal sectional elevation of the same. Fig. 5 is an inverted sectional plan view of part of the fire-box and its connection with the mud-ring, the section being on the line 5 5 of Fig. 3; and Fig.6 is a plan view of the mud-ring. V

The shell A of theboiler is provided with a wagon-top B, within which extends a firebox 0, connected at its forward end with the rearflue-sheet D for the usual boiler flues or tubes E,'the said wagon-top B, fire-box (J, and, flue-sheet D being connected with a rectangular skeleton frame or, as ordinarily called, a mud-ring. F in such a manner that the fire-box is supported wholly independent of the wagon-top and a clear unobstructed space is had between the fire-box and the wagon-top, as hereinafter more fully described. I

The fire-box O is formed of sections C, arranged one alongside the other and each in the form of a segment of a circle, as plainly indicated in Fig. 3, the sections having their peripheral bodies bulged inwardly, as plainlyshown in Figs. 1 and 4t, and each section C is provided with.outwardly-extending connecting-flanges C for fastening the several sections together, a segmental packing or calking ring G being interposed between the flanges of adjacent sections C, as plainly indicated in Fig. 4, the flanges and calkingring being fastened together by rivets or similar fastening devices. The terminals 0 of each section O are straight or in the shape of flanges abutting against the inner faces of the side bars F of the mud-ring F, and the sides of each terminal C are beveled, so that the beveled sides of adjacent terminals C overlap each other, as will be readily understood 'by reference to Fig. 5.

The terminals C are fastened to the side bars F ofthe mud-ring-by bolts H, which also fasten the terminals of the segmental wagontop B to the Outer faces of the sidebars F of the said mud-ring. In order to cover the joints or overlapping sides of the terminals C ,v covering-strips I are provided, interposed between the inner heads of the bolts H- and the inner faces of the terminals C as plainly shown in Figs. 3, 4:, and 5, and in order to strengthen the wagon-top reinforcing-strips J are interposed between the terminals ofthe wagon-top and the outer faces of the side bars F, and the said reinforcing-strips J are in addition attached by bolts J to the wagon-top (see Fig. 3.) v

By the arrangement described the fire-box is supported from the side bars of the mudring, and by giving the peculiar shape to the sections G of the said fire-box it is not necessary to employ stay-bolts or the like for connecting the fire-box with the wagon-top.

As illustrated in Fig. 6,'it will be seenthat the mud-ring F is formedof a single piecethat is, the side bars F are integrally connected with each other by the front cross-barF and the rear cross-bar F and on the bottom faces of the side bars F are formed lugs F for supporting a grate K and an ash-pan L, as indicated in Fig. 1. The forward cross-bar F is in the shape of a segment of a circle, the curvature. extending downwardly, the top face of the cross-bar F being engaged by the lower portion of the flange D of the fluesheet D, and the under side of the said front cross-bar Fiis engaged by the lower portion of the forward end of the wagon-top B, the same rivets being used for fastening the flange of the flue-sheet D and the wagon-top B to' the said forward cross-bar F The side bars F of the mud-ring are formed at their upper corners with cut-out portions F (see Fig. 4:.) for accommodating the flanges O and callring-rings G to allow the said flanges and calking-rings to rest on the side bars F of the mud-ring.

The back ring B of'the wagon-top B is curved rearwardly and downwardly, as indicated in Figs. 1, 2, and 4:, and the terminals of this back ring B engage the outer faces of the side bars F of the mud-ring F the same as the wagon-top, and the rear end of the said back ring B is closed by a back head B fastened to the rear cross-bar F of the mudring F. The back ring B is provided with an inner plate B having a longitudinally-extending flange B, connected with the rear end of the rearmost section G of the fire-box, and the said plate B forms, with the back ring B, a fire-door opening The lower ends of the back ring B and its reinforcingplate B straddle the rear of the cross-bar F of the mud-ring to firmly connect the entire wagon-top with the mud-ring in the manner above set forth.

By arranging the inner and outer faces of the side bars F of the mud-ring in the manner describedthat is, in the plane of the terminals of the segmental wagon-top and firebox sections Oit is evident that an exceedingly strong connection is made between the several parts, and the said terminals can be readily connected to the mud-ring without forming angular joints and the like.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1.
